Morgan was allegedly partying in the East End before being pulled over in her 2006 BMW by a Southampton police officer at 2:16 am early Monday morning for failing to stop at a stop sign.

After failing several field sobriety tests and refusing to take a Breathalyzer test, she was processed and held for morning arraignment, Southampton police said.

Morgan pleaded not guilty to misdemeanor driving while intoxicated. She also is accused of driving without a fastened seatbelt, failure to keep right, and failure to stop at a stop sign.

She later was released without bail and is due back in court on June 21.

Attorney Edward Burke says he intends to "vigorously defend her."

hile it is Morgan's first season on "Real Housewives of New York City," which is in its third season -- this isn't her first run in with the law .

In 2008, Hannibal Pictures said that Morgan -- who is the ex-wife of John Adams Morgan, the grandson of the infamous J.P. Morgan -- had agreed to finance a 2006 movie, but had backed out at the last minute because her divorce had just begun, the New York Post reported.

The divorce was finalized in 2008 and in September of that year Hannibal Pictures won a suit against Morgan for $7.06 million in damages. The movie was never made.

"Real Housewives of New York City" is one of a set of reality TV shows aired on Broadway that follow upper-class women -- not all of them housewives. Other versions of the show feature women from Orange County, New Jersey, Beverly Hills, and Washington, D.C.

The show airs on Bravo, which is owned by NBC Universal, the parent company of NBCNewYork.com. A Bravo spokeswoman said they "do not comment on the personal lives of our talent."
